Agelaioides fringillarius
The Pale Baywing, *Agelaioides fringillarius*, is a captivating medium-sized icterid, endemic to the open woodlands and agricultural landscapes of central and eastern South America. Measuring approximately 18-20 cm (7-8 inches) in length and weighing between 40-50 grams, this species exhibits a rather understated elegance. Its plumage is predominantly grayish-brown, subtly contrasting with a diagnostic pale yellowish-buff to whitish carpal patch on its wing, a key field mark that distinguishe...
This adaptable species favors open woodlands, savannas, grasslands with scattered trees, agricultural fields, and suburban parks. It typically occurs at elevations from sea level up to around 1,000 meters (3,300 feet).

They exhibit a varied foraging strategy, gleaning insects from foliage, probing the ground for invertebrates, and consuming seeds d...
The Pale Baywing is broadly distributed across a significant portion of central and eastern South America. Its breeding range extends from eastern Bolivia and Paraguay, throughout much of Uruguay, and across vast areas of central and northeastern Argentina. In Brazil, it is found from the states ...
